This invention relates to new and ueetul ii'njnoveniente in a railway rail joint.

One object ol1 the invention is to provide novel joint ot the character doscril'ied speci-- ally designed ttor uniting railway rails securelv together without the use out heh platee and so that the oiut will not Sag' or shear the holte incorporated into the joint. v

Another object ot the invention in to jard vide a oint ot 4"he character described which will he very strong and will provide a smooth tread, and whielnat the saine time is et siinple structure so that it inay he readily aseernhled. Y 1 A further object ont the invention resides in the provieion ot a novel and eliicient type xoit railhfav rail joint with whichthe. rails ot a track ihay he equipped at comparatively small expense. f

lll ith the alcove and other objects in View this; invention has particular relation to cer tain novel features of construction, arrangeinent of parte and use en example et which is given in this specification and illnetrated in the accompanying drawinge wherein:

Fie-ure l shows a plan vieivjo'l ahutting rails connected hy the novel type otjoint. i

The;1 i rails; are ot conventi onal construction except as hereinafter pointed out, having the treads Z the Wehe 4r and the hoses 5. t one end the'hase 5 of the rail 2 is extended hevond the web and tread thereoil 'forming the heee e eneion El Whose upper side forine a flat face and upstanding; from said extension, at! one eide of Said tace there 31e a tenen 8, coen isive in length With the hase entension and integrally joined to said extension as Well as to the adjacent end ol the rail 2, proper. This hase extension 6, is considerahly thicker than the rail hase 5., to give additional. Strength to the joint.

Serial No. 311,360.

rlhe adjacent end of the rail l has a tread extension 9 which entends hejiond the correspending;v end of the hase 5, el? said rail and whoee underside has; the tace l0, at one eide, and the depenffling tenen ll, at the other eide, each, coextensive, :in length with said tread extension and said teno'n ll being vformed in ten-rally with said tread extension and with the adjacent end oil. the rail l proper.

.When assembled together the tread extern eion 9 ahnte the opposing end olE the tread ol the rail?l and the tenons 8, ll overlap With the ripper edge ot the tenen 8 tittini.;l closely against the it'ace l0 throughout and the lower edge ol the tenen ll littinp; closely1 against the tace throughout, and ivhen so :iesen'ihled the free end olf each tenen ahnte against the opposingv vertical shoulder lf3 ol;I the other rail Said shoulders l2 being formed hiv thiclieningjg the rail Wehe l. adjacent the joint, to the full Width oi"v the rail tread 3.

The i'ace l0, and the abutting` edge of the tenen tl are formed, one with a lengthwise groove 13 and the other with fa lengthwiee head, or rih, 141 which. conforms to the contour of and adapted. to lit into said groove, thus providing interloellring' parte which assist in holding the over]sipping1 tenone against spreading. The adjacent sides ot Said tenons are provided one with a lengthwise groove .5 and the other with a longitudinal rih 1G adapted to Seat in Said groove l5, when the joint ie aeeeinhled. These interlocking parte naeiet in preventin; the joint frein Sasi'einnj under a load ae Well jinevent the nhearinn; oli the securing holla l? which Secure the over'- lappine' tenons; t( ,'ther. `'lhe holte naar: through registering; holen lil en idingr transfvereeljr through easid tenonfn and which are elongated, longitinlinallj/ ot the tenons lo permit the required longitudinal movement oft the rails due to variations; in temperature.

llihile l have shown and de.. rihed what I nowconeider the preferred forno of this invention it is ohvloue that mechanical changea; inay he made in the structure thereof and I reserve the right to inale such Struc|- tural changes as may he comprehended with` the principle of the invention.
